Signs are visual symbols or messages that convey information or instructions. They can be found everywhere, from road signs that guide drivers to store signs that help customers find what they need. Signs use simple images or words to communicate quickly and effectively, making it easier for people to understand their surroundings. In addition to practical uses, signs can also express ideas or emotions. For example, protest signs are used to share messages about social issues, while advertising signs promote products and services. Overall, signs play a crucial role in our daily lives by helping us navigate and connect with the world around us.
